Application filed May 14, 19324; Serial ,No. 713,214;

To all whom it may concern:

Be it known that I, WILLIAM L. DENTON, a citizen of the United States, residing at Randsburg, in the county of Kern and State of California, have invented new and useful Improvements in Orthopedic Apparatus of which the following is a specification.

My invention relates to orthopedic apparatus and consists of the novel features herein shown, described and claimed.

The objects and advantages will appear from the drawings and specification.

The drawings illustrate the invention. Figure 1 is a perspective showing an orthopedic apparatus embodying the principles of my invention in use in connection with a hospital cot or the like and a Baltic frame, the operation shown being preliminary to the setting of a broken leg and ap-. plying the cast. r i

Fig. 2 is an enlarged detail plan of the stretchingappar'atus parts being shown in section.

Fig. 3 is a side elevation looking in'the direction indicated by the arrow 3 in Fig. 2.

Fig. 4 is a sectional detail on theline The details bf the orthopedic device 8 shown in the drawings are as follows:

The cot or bed 1 may be any of the ordinary constructions having a head. frame 2 and a foot frame 3. The Baltic frame 4 may be of the ordinary construction having upper side bars 5 and 6 and is mounted upon the head and foot frames 2and 3. Pulleys are connected to rings 9 and 10, said rings sliding upon the side bars 5 and 6 near the head of the bed 1. Ropes 11 and 12 run over the pulleys 7 and 8 and have blocks 13 and hooks 14, as required to form blocks and tackles, the free ends 15 of the ropes serving to operate the blocks and tackles.

Ina like manner, blocks and tackles 16 and 17 are mounted upon the rear ends of. the I side bars5 and 6.

The rectangular stretcher frame 18 isv constructed of pipe and elbows andv clips 19 are fixed upon the'sideibars of the .stretcher 1 8 andhave upwardly extending ears to receive the hooks -14 of'the blocks Y from tipping.

and tackles so that by manipulating the I ropes 15 the stretcher may be raised pr lowered. A canvas 20 is stretched upon the frame 18 and has a central opening 21.

The folding and extensiblesho ulder sup. port and head rest 22 is mountedupon' the side bars of the shoulder frame '18 and may be elevated to support the shol ildersand head of a patient. p Y I Usually the patient having 'a'broke'njleg or the like is placed upon the portable ed p e bed 1 and thedetails are 'as follows: H v

"stretcher 18 and brought to the "bed; The leg stretcher and body support 34"is mount- A board" 35 rests upon the mattress and extends across the bed to prevent the frame.

A block 36 "is rigidly secured to the center of the board 35 and extends upwardly and has afiat upper face 37.. i A- flange base 38 rests upon the' boa'rd35 in front of the block'36 and is removablyjsecured in placelby bolts and'wi'ng nuts'39.

A socket 40 extends upwardly'from the base 38 and is internally screw threaded'.'lhe I removable post 41 is screwed down into the socket 40. A long sleeve 42 extendsfrom the base 38 towards the foot of thebedand hasa boss 43 carrying the thumb head set screw 44. The extension bar 45- is "slidingly mounted in theslee ve 42 and has depressions46 to ,receivethe point of thef 'set screw 44 so that byloosening the set screw 44 the bar 45 may be adjusted inwardlyf or outwardly in the sleeve 42 and thefset screw 44 tightened to hold the bar 45 from rota tion and from endwise movement} An elbow 47 fits loosely upon the-foot end of the I bar 45 and is held removably in place by a pin 48. A second post 49isfixedfinthe .elbow 47 and extends upwardly parallel with the post 41,. A T 50'has its side opening 5l,"adapted' to receive thefupperend of the-post. 49"an'd the T is held securely 'placeby afpin 52, apemg- "especially. important that the T' 50 and 'the".fpost' '49 i shall :not rotate relative to extension bar 45; 'Arms 53 and '54. are" rigidly mountedin theends ofjtlre TI5O andexte'ndj out.

, wardly into the vertical planes j containing the sides of the frame 18. The adjustable heel clamps 55 and 56 are pivotally connected to set collars 55 and 56 slidingly and adjustably mounted upon the outer portions of the arms 53 and 54. The pivotal connections consist of attaching plates 57 and 58 fitting upwardly against {the set collars 55 and 56 and secured in place by pivots 59 and 60.

Bearing plates '61 and '62 extend down- Wardly from the forward ends of the attaching plates 57 and 58. Long adjusting screws 63 and 64 are mounted loosely through the bearing plates '61 and 62. Crankhandles 65 and 66 are formed integral with the outer ends of sleeves 67 and 68 and each sleeve 67 and 68 has a nut 69 at its forward end to work upon the screws 63 and 6 1 behind the bearing plates 61 and so that by manipulating the hand cranks 65 and '66 the screws 68 and 6% may be 0perated to pass backwardly or forwardly fork 71 has clamping screws 76 and through the bearing plates 61 and 62. Forks 7 O and 71 are s'wiveled to the screws and 6 1 byjoints 7 0 and 71 and extend forwardly from the ends of the screws 63 and 64 and clamping screws 72 and 73 are mounted through the ends of the prongs of the fork 70 and have pads 74: and 75 upon their inner ends. In a like manner, the

upwardly. The post 41 will be placed into the socket 40, the extension bar will be adjusted approximately to the proper length, the hand cranks 65 and 66 will be operated to move'the foot clamps forwardly,

then the ropes 15 will be operated to lower the stretcher 18 so that the post 41 and I block 36will pass upwardly through the bone at the upper end of the crotch.

ope'ningi21 in the stretcher cover 20 and.

the block supporting face 37 will engage the lower end of the spine of the patient and the post 11 will pass upwardly between the patients legs and engage the .pelvic Y The feet will be placed in the foot clamps 55'and 56,- the thumb screws 72 and 73 and 76 and 77 operated to grip the heels of the feet and the handclamps and 66 operated to pull upon the feet to .pull the post 41 intofthe'crotch and stretch the legs to the desired extent. The head and shoulders of thepatient will be raised at the proper time and the support 22 elevated to sup port the head and shoulders, all as shown in Fig. 1. The blocks and tackles may be disconnected at any time during this operation.

7 If the patients thigh bone is broken and the ends 8O and 81 overlapped th'eleg may be stretched and rotated and abducted or adducted to bring the ends 80 and 81 into line for setting, as shown in Fig. 1. Numerous other operations may be performed as "required by the case.

The apparatus allows either internal or external rotation, and tensioning adducting and abducting. The desired position can be maintained while a east reaching from the axilla to and including the feet can be applied. Then the Bradford frame can be raised to support, the body as the shoulder disturb the cast while the plaster hardens.

The hole in the frame allows massage of the sacral region and the use of a bed pan by raising the frame by pulleys attached to the Baltic frame without disturbing the vpatients position. tus rests on the bed and is prevented from turning sideways by the transverse bar.

Various "changes may be made without departing from the spirit of my invention as claimed.

I claim:

1. In an orthopedic device a leg stretcher and body support comprising a board adapted to rest crosswise upon a bed, a block extending upwardly from the board and adapted to support the lower end ofa patients spine, a removable post extending The orthopedic apparaupwardly from the board beside the block,

an adjustable extension bar extending horizontally from the board a second post ex tending upwardly from the foot end of the extension bar,a cross bar at the upper end of the second post, supporting bearings pivotally connected to the ends of the cross bar, screws slidingly mounted through the bearings, hand cranks having nuts upon the screws behind the bearings, forks at the forward ends of the screws, clamping screws in the forks and adapted to engage a patients feet so that when a patient is in position the legs may be stretched by operating the hand cranks. V

2. In an orthopedic device a leg stretcher and body support comprising a board adapted to rest crosswise upon a bed, a

block extending upwardly from the -board zontally from the board, a second post extending upwardly from the foot end of the extension bar, a cross bar at the upper end of thesecond post, supporting bearlngs pivotally connected to the ends of the cross bar, screws slidingly mounted through the bearings, hand cranks having nuts upon the screws behind the bearings, forks swiveled at the forward ends of the screws, clamping screws in the forks and adapted to engage a patients feet so that when a patient is in position the legs may be stretched by operating the hand cranks so as to support a patient above the bed for tensioning, adducting, abducting and rotating the lower extremities and applying a cast.

In testimony whereof I have signed my name to this specification;
